Mazda RX-7 is a sports car produced by the Japanese automaker Mazda from 1978 to 2002. The original RX-7 featured a 1146 cc twin-rotor Wankel rotary engine and a front-midship, rear-wheel drive layout. The RX-7 replaced the RX-3 (both were sold in Japan as the Savanna) and later replaced all other Mazda rotary-engine cars except the Cosmo.
The original RX-7 was a sports car. The compact and lightweight Wankel engine (rotary engine) is situated slightly behind the front axle, a configuration marketed by Mazda as "front mid-engine". It was offered as a two-seat coupé, with optional "occasional" rear seats in Japan, Australia, the United States, and other parts of the world. These rear seats were initially marketed as a dealer-installed option for the North American markets.
